Researchers trace evolution to relatively simple genetic changes

...marine population." So, he said, "the marine fish actually carry the genes for this alternative state, but at such a low level it is never seen;" all the ocean fish remain well-armored. "But they do have this silent gene that allows this alternative form to emerge if the fish colonize a new freshwater locati...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

New SARS Protein Linked To Important Cell Doorway

...se, and the researchers had no proof yet that SARS actually made use of the sequence their analysis identified. Geneticists call such sequences of genetic information open reading frames, and the SARS sequence therefore came to be known as open reading frame 7a, or orf7a. To produce the orf7a protein, resear...

NC State scientist finds soft tissue in T. rex bones

...entire fossil. But the team was surprised by what actually happened when they removed the minerals from the T. rex femur fragment. The removal process left behind stretchy bone matrix material that, when examined microscopically, seemed to show blood vessels, osteocytes, or bone building cells, and other rec...

UCSD discovery may help extend life of natural pesticide

... "This latest paper demonstrates what these sugars actually do. They provide a receptor for the toxin that allows the toxin to recognize its "victim"--a roundworm or an insect. This paper also brings us from the conceptual realm to the chemical nature of these sugar structures--how their atoms are arranged, a...

Scientists identify new model Of NK cell development

...boratory shows that the precursors to NK cells are actually found in cellular nurseries deep inside the body's lymph nodes. The findings, appearing in the Mar. 22 issue of the journal Immunity, may offer clinicians new direction in determining how to manipulate this cell type in enhancing immune responses to...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...en we open up the hood of these three organisms we actually have selective and poor vision," said Ideker. "Nevertheless, when we found protein interactions and communication pathways conserved across all three species we were more confident that we are seeing something real." Biologists have known for many y...

Falling ants glide back to trunk to avoid dangers of forest floor

...k a few feet and occasionally bounce off. They can actually make 180 degree turns in midair, however, so even when they fail the first time, they can execute a mid-air hairpin turn and glide in for another try. "It's an amazing discovery," said Robert Dudley, a UC Berkeley expert on flying and gliding creatu...

Gene therapy for Parkinson's disease moves forward in animals

Scientists find fossil proof of Egypt's ancient climate

...lars to predict the severity of winter, the snails actually reveal clues about the climate and environment of ...ago, what everyone considers an eternal desert was actually a thriving savannah, complete with humans, rhinos, giraffes and other wild life. Evidence for the h...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...t therapeutics directly to a tumor, enabling us to actually see if chemotherapy is really going to its intended target." This work takes advantage of years of effort in the Therien laboratory focused on the design of highly fluorescent compounds. Polymersomes, which were developed by Penn professors Daniel A...

Special Imaging Study Shows Failing Hearts Are 'Energy Starved'

...ATP, we believe this is the first time someone has actually measured the flux of ATP produced by CK reaction in the beating human heart.?/p> Specifically, Bottomley and a team of cardiologists and radiologists at Hopkins used MRS to provide direct molecular-level measurements of the CK supply in normal, s...

Sexual cooperation: Mating increases longevity in ant queens

...t queens of the social ant Cardiocondyla obscurior actually benefit from mating by gaining increased lifespan and reproductive success, living longer irrespective of whether males could transfer viable sperm or had been sterilized prior to mating. It remains unknown how mating increases the longevity of the f...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

... of these rare broadly neutralizing antibodies are actually polyspecific autoantibodies that react with many proteins, including one's own tissues, like the antibodies made by innate B cells. In laboratory tests, the antibodies reacted with multiple types of human molecules, most prominently with a fat molecu...

Genetically modified rice in China benefits farmers' health, study finds

...-based information about whether GM food crops can actually improve farmer welfare," Pray said. He and colleagues set out to conduct an economic analysis of data from eight rice pre-commercialization field trials in China. Their goal was to determine whether genetically modified rice was helping farmers redu...

Vampire bats keep out of trouble by running

...ting most of the push from their long forelimbs -- actually their wings and therefore very strong -- the bats run more like a small gorilla than a comparable four-legged creature like a mouse. They run up to about 2.5 miles per hour. Although many of the 1,100 species of bats are known to walk, the common vam...

A new study examines how shared pathogens affect host populations

...pathogen among one or more alternative species may actually be limiting the spread of the pathogen in any one particular host population. Thus, an epidemic on one species may result because of loss or reduction in the abundance of species in the community, without any numerical or genetic change in the host o...

Drug-resistant bacteria on poultry products differ by brand

Price explained that previous epidemiological studies have indicated that fresh poultry products are a major source of Campylobacter infections in humans. Exposure can occur from undercooked products or through cross-conta...

PET/MRI scans may help unravel mechanisms of prenatal drug damage

...n medication to the fetus via the placenta. But we actually do not know if what we give is sufficient to 'satisfy' the pain level of the fetus," said Benveniste, who is also a professor of anesthesiology at Stony Brook University. Though other scientists have attempted to use PET to noninvasively monitor mat...

Chemists identify immune system mechanism for methamphetamine binges

...iety. "Test animals injected with methamphetamine actually developed antibodies to the drug, which is highly unique for a molecule of its relatively small size," says study co-leader Kim Janda, Ph.D., a chemist at Scripps in La Jolla, Calif. Developing antibodies to the body's invaders, such as viruses and b...
